What is complementary color matching with pictures

Quick answer：

Complementary color matching in design refers to the practice of pairing colors that are directly opposite each other on the color wheel. This creates a high-contrast, dynamic look. In a picture, complementary colors are used to create visual interest and to draw attention to certain elements. It involves selecting colors like blue and orange or red and green, which, when placed next to each other, can enhance the visual appeal and convey a strong emotional response.
